We used the plans from Hose2Habit. Check them out here for detailed instructions.
How to use: We hide a variety of food, object enrichment and browse in the cube pockets
Price: We used free recycled firehose from our local fire department. These are only a few dollars each to purchase the hardware.

I just love watching the Chimps grow and change from complacent test subjects to free spirited chimps. I never realized they were so big. It is definitely inspirational to see the hope that grows in them. I just wish they could have experienced that for their whole lives not just the end. Keep up the good work.
